@Shovel: Well, my set of Snover wasn't really "offensive", it's just he can't just take hits, 60/50/60, he had even worst deffensive stats/type than Beautifly, and Beautifly is the biggest definition of paper thin bulk. Of course, Eviolite can, on theory, make him able to take at least 1 resisted hit, as long that hit is not being boosted by anything and it doesn't be a powerful attack at all, and... water attacks, and that is. Eviolite Snover is only better than any other Snover on... well... making problems to Mono-Water-Type attackers, and that's excesive strange, even Alomomola tends to run a second type to attack (even Alomomola with Toxic will win the 1vs1, unless the opponent is stupid). But yeah, he'll fall against everything on the tier who is not mono-water-type attacker, or even against them, two powerful Hydro Pumps still K.O Eviolite Snover. And of course, Stealth Rock/Spikes/Toxic Spikes will destroy the already minimal bulky it has.

The Choice-Scarf set AT LEAST can do something against some things, like anything weak to grass to start off, and anything (incluiding Alomomola) who needs of status to make damage or being of help to the team, and anything who needs 2 or more turns to make something, and make a good place to revenge kill someone, too, because Snover is unnable to hit a K.O otherwise. Generaly, on the 99% of times, Snover will just bring hail and being K.O soon or after, but with Choice Scarf he CAN do something before him's fall, because he's able to outspeed a good portion of the tier in that way, and it also clean the path to better switchs of it's useful partners. The Focus Sash variant is almost the same, but it can do more damage with Blizzard (better for revenge killing) and sometimes bring the hail for third time on mid game, but in exchange, it needs a seriously Rapid Spin/Taunt support (while the Eviolite variant depends totally of it, too).

And over all things, it prevents Snover to being transformed into Taunt Bait and/or to give free turns to the opponent to set up, he can destroy the substitute of sweepers with max investment Wood Hammer, and can use Leech Seed when they set up (or when they belive the can taunt it, and he outspeed them), and in the worst scenary, Snover will just K.O itself with the recoil, giving you a free switch.

Anyway, Hail is not a big threat, it's very easy to deal with it, but it does help to some Pokémon to have real competitive oportunities.
